Subject: [PATCH 0/3] mm: Fix bug affecting swapping in MTE tagged pages
Date: Fri, 12 May 2023 16:57:49 -0700 [thread overview]
Message-ID: <20230512235755.1589034-1-pcc@google.com> (raw)
This patch series reworks the logic that handles swapping in page
metadata to fix a reported bug [1] where metadata can sometimes not
be swapped in correctly after commit c145e0b47c77 ("mm: streamline COW
logic in do_swap_page()").

Peter Collingbourne (3):
mm: Move arch_do_swap_page() call to before swap_free()
mm: Call arch_swap_restore() from arch_do_swap_page() and deprecate
the latter
arm64: mte: Simplify swap tag restoration logic and fix uninitialized
tag issue
